Notice how "y" is not present in the equation. So what is saying is that x-coordinate must be equal to 4, but y-coordinate can be any number. This means that the equation generates the table

x	y
4	-5
4	-4
4	-3
4	-2
4	-1
4	0
4	1
4	2
4	3
4	4

And if we plot these points, we get

So this results in a vertical line through .
